ST/STC series AC synchronous generator operation and maintenance manual
STC series three-phase AC synchronous generator
This series of generators and internal combustion engine can be used as fixed or mobile small power stations for rural, urban or construction sites, pastoral areas, etc., as lighting and power supply.
This series of generators is three-phase star connection with neutral point, line voltage is 400V, phase voltage is 230V. Frequency 50HZ, power factor 0.8(lag). According to user needs, 60Hz and other voltage generators can also be provided.
This series of generators can be directly connected with the prime mover or connected with a triangular belt. The generator can be turned in both directions. Continuous rated operation. In order to make the generator normal operation to generate electricity, please read this manual carefully before use.
In addition, we also have diesel engines with 220v voltage

This series of generator adopts harmonic excitation, in addition to the main winding on the stator core, there is another set of harmonic winding, which is rectified by the three-phase bridge silicon rectifier and then passes into the magnetic field winding for excitation. Since the third harmonic voltage will increase correspondingly when the motor is loaded, the self-excited constant voltage performance can be achieved without any other complex automatic voltage regulator.
This series of generators has excellent dynamic performance. It can directly start 0.7 times capacity squirrel-cage asynchronous generators without any additional starting gear transposition.
